    Overview

    Cisco C1-C6840-X-LE-40G Overview

    The Cisco C1-C6840-X-LE-40G is an enterprise-class switch engineered to deliver advanced performance, scalability, and security for demanding enterprise network infrastructures. Centered on the needs of modern data environments, it integrates robust management and comprehensive Layer 2/3 services, supporting seamless transitions between traditional and cloud switch architectures. Its native QSFP+ capabilities ensure high-density uplinks for bandwidth-intensive applications, providing efficient interconnections for cloud-driven operations. The switch offers a substantial switching capacity of 240 Gbps in full duplex mode and a hardware-accelerated forwarding rate of 180 Mpps, making it suitable for high-volume traffic typical in contemporary enterprise network environments. Cloud switch deployments benefit from automated management interfaces, including CLI, SNMP, NETCONF, and REST API, allowing flexibility for IT teams of different sizes. Large enterprise network infrastructures leverage up to 40 native 10G ports and 2 dedicated QSFP+ 40G uplinks to optimize backbone connectivity. Comprehensive hardware-level security features, such as MACsec and 802.1X, deliver critical protection for sensitive data traffic. The switch’s 2RU rack-mountable design, redundant power and fan support, and robust buffer architecture ensure reliability and operational continuity for mission-critical QSFP+ deployments. With these attributes, the C1-C6840-X-LE-40G provides a scalable solution for businesses that aim to modernize their enterprise network, streamline cloud switch connectivity, and future-proof network investments for diverse regional requirements in Asia, Europe, North America, and Africa.
